I think it's important to think about all of your experiences ( especially those where you were a leader ; if you don't have any , its ok) and think about the skills you used and the ones you learned during your time. Everyone has leadership skills and abilities , so don't make the interview about the skills you HAVE, instead make it about how you learned and how valuable the skills are to you. Everyone doesn't acknowledge their ignorance ( or are too embarrassed to do so) ; This is your opportunity to be mature with a different angle. Think about them. Claim them. Embody Them. Share Them. I call it, Reflection.
